I recently purchased a NEI mold the mold is in great shape but it didn't come with any screws to hold it on the handles. I have several Lee and a RCBS mold and none of the screws from them will work. I was going to get one from the hardware store but the screws are counter sunk into the mold and I cant find anything like what should work. Anybody know what type of screw will work or where to source them?
